The Ginlong Solis S6-EO1P series are single-phase grid storage inverters designed for off-grid operation, where full grid independence and reliable island mode power supply for homes or facilities are essential. What distinguishes them is their flexible cooperation with an energy storage system in a low-voltage architecture, along with the ability for rapid configuration even for batteries without communication, facilitating component selection in practical projects.
The application of 2 MPPT allows for better utilization of the yield from two independent module strings-such as in cases of different roof orientations or seasonal shading. High European efficiency translates to significantly better performance in typical climatic conditions in Poland, not just in laboratory settings.
A major advantage is the remote monitoring and diagnostics via the platform and app, supporting popular communication methods (including WiFi and wired solutions). The series offers comprehensive safety features, complete with required safety and EMC certifications, and warranty conditions expected for home and small commercial installations.

Pros and cons
The series allows for the connection of up to 6 inverters in parallel, creating an island system with a power output of up to 36 kW - without the need for a separate master controller. This is a rare feature in this power range (4-5 kW per unit) and a key advantage for commercial installations or large farms operating off-grid.
The inverter can withstand temporary overloads of up to 200% of its rated power for 10 seconds, which allows for the smooth start of electric motors (pumps, compressors, saws). Most competitors in the low-voltage segment (e.g., Deye SUN-5K-SG01LP1) claim a tolerance of 110-150%.
The device offers a mode of operation with batteries without active communication with the BMS (e.g., older LiFePO4 or AGM/gel batteries), with the ability to manually configure charging parameters. This eliminates the need to purchase batteries with their own protocol and reduces the overall system cost.
Two independent off-grid power outputs allow for the intelligent separation of critical loads (e.g., refrigerator, lighting) from secondary loads. In the event of a low battery state of charge, the system can automatically disconnect less important circuits, thereby extending the operational autonomy of the installation.
Ginlong (Solis) has been listed on BloombergNEF's Tier 1 PV Inverter Manufacturers list for several consecutive quarters (most recently confirmed for Q1 2025), and is the 3rd largest global manufacturer of photovoltaic inverters. This translates to a realistic project bankability, availability of spare parts, and stable technical support over a 10-15-year period.
The standard manufacturer warranty is 2 years, while companies like Deye, Victron Energy (MultiPlus-II), and Studer offer 5 years as standard. For off-grid installations, where the inverter is the sole power source for the property, a shorter warranty period significantly increases the potential costs of maintenance or the need to purchase an extended warranty at an additional cost.
With a power of 5 kW, the DC current from the battery reaches approximately 100 A (5000 W / 48 V), which requires cables with a cross-section of ≥50 mm² and high-quality connectors. In comparison to high-voltage systems (e.g., 200-400 V DC), the material costs for the battery-to-inverter cabling can be 2-3 times higher, which should be factored into investment calculations.
